Apple is set to begin pre-orders of the next-generation iPhone 5 on September 12, according to iMore. You might recognize that date as being the same day that Apple will unveil its next smartphone to the world, so it looks like pre-orders will begin later that day. The smaller 7.85-inch iPad is also heavily rumored to make an appearance on 9/12 as well. The next iPhone is expected to see a September 21 release, with international sales kicking off on October 5.
